The BS program coordinators wanted to understand the difficulty level of the BA course. Hence, past learners of the BA course were asked to give a rating (on a scale of 1 to 5, 1 meaning “least difficult” and 5 implying “most difficult”). A total of 200 students (100 male and 100 female) were approached for the survey and the result of the same is provided in Table-1
Given this data, answer the given subquestions.

Table-1

If the focus is on seeing the proportion of responses of each gender in each difficulty level, then which among the following graphs will be best suited? (Note: While choosing an answer to this question, please do not worry about colour reproduction or other aesthetics. Make a choice only based on the concepts of visualization theory)

Table-1

If the aim is to determine if the difficulty level is independent of gender, then how many male responses would you expect to choose the rating value of “4”? (Round your answer to two decimal places. Eg: If your answer is 10.256, then round it to 10.26)
